I've double-checked that it goes to 'copy_timeout' in ts-conf/rcf.conf. Description in in doc/sphinx/pages/group_te_engine_rcf.rst says that copy_timeout is in seconds and implementation in lib/rcfunix/rcfunix.c passes the value to select() tv_sec. Theoretically select() could be interrupted by signal, but I think it is unlikely here. I'm not sure that I understand what do you mean by RCF connection timeout. Does it happen on TE startup when RCF starts test agents. If so, TE_RCFUNIX_TIMEOUT could help. Or does it happen when tests are in progress, e.g. in the middle of a test. If so, TE_RCFUNIX_TIMEOUT is unrelated and most likely either host with test agent dies or test agent itself crashes. It would be easier for me if classify it if you share text log (log.txt, full or just corresponding fragment with some context). Also content of ta.DPDK or ta.Peer file depending on which agent has problems could shed some light. Corresponding files contain stdout/stderr of test agents. Andrew.

Hi Andrew,

I've set up a test rig repository here, and have created configurations for our development testbed based off of the examples.
We've been able to get the test suite to run manually on Mellanox CX5 devices once.
However, we are running into an issue where, when RCF starts, the RCF connection times out very frequently. We aren't sure why this is the case.
It works sometimes, but most of the time when we try to run the test engine, it encounters this issue.
I've tried changing the RCF port by setting "TE_RCF_PORT=<some port number>" and rebooting the testbed machines. Neither seems to fix the issue.

It also seems like the timeout takes far longer than 60 seconds, even when running "export TE_RCFUNIX_TIMEOUT=60" before I try to run the test suite.
I assume the unit for this variable is seconds?

Thanks,
Adam

Hi Adam,

I've published https://github.com/ts-factory/ts-rigs-sample. Hopefully it will help to define your test rigs and successfully run some tests manually. Feel free to ask any questions and I'll answer here and try to update documentation.

Meanwhile I'll prepare missing bits for steps (2) and (3).
Hopefully everything is in place for step (4), but we need to make steps (2) and (3) first.

OK, I'll provide the sample on Monday for you. It is almost ready right now, but I need to double-check it before publishing.

We do want to run testing on a regular basis. The Jenkins integration will be very useful for us, as most of our CI is orchestrated by Jenkins.
I've conferred with the rest of the team, and we think it would be best to move forward with mainly option B.
If you would like to know anything about our testbeds that would help you with creating an example ts-rigs repo, I'd be happy to answer any questions you have.

We have multiple test rigs (we call these "DUT-tester pairs") that we run our existing hardware testing on, with differing network hardware and CPU architecture. I figured this might be an important detail.

Thanks,
Adam

Greatings Adam,

I'm happy to hear that you're trying to bring it up.

As I understand the final goal is to run it on regular basis. So, we need to make it properly from the very beginning.
Bring up of all features consists of 4 steps:

1. Create site-specific repository (we call it ts-rigs) which contains information about test rigs and other site-specific information like where to send mails, where to store logs etc. It is required for manual execution as well, since test rigs description is essential. I'll return to the topic below.

2. Setup logs storage for automated runs. Basically it is a disk space plus apache2 web server with few CGI scripts which help a lot to save disk space.

3. Setup Bublik web application which provides web interface to view testing results. Same as https://ts-factory.io/bublik

4. Setup Jenkins to run tests on regularly, save logs in log storage (2) and import it to bublik (3).

Last few month we spent on our homework to make it simpler to bring up automated execution using Jenkins - https://github.com/ts-factory/te-jenkins
Corresponding bits in dpdk-ethdev-ts will be available tomorrow.

Let's return to the step (1).

Unfortunately there is no publicly available example of the ts-rigs repository since sensitive site-specific information is located there. But I'm ready to help you to create it for UNH. I see two options here:

(A) I'll ask questions and based on your answers will create the first draft with my comments.

(B) I'll make a template/example ts-rigs repo, publish it and you'll create UNH ts-rigs based on it.

Of course, I'll help to debug and finally bring it up in any case.

(A) is a bit simpler for me and you, but (B) is a bit more generic and will help other potential users to bring it up.
We can combine (A)+(B). I.e. start from (A). What do you think?

Thanks,
Andrew.

Greetings Konstantin,

I am in the process of setting up the DPDK Poll Mode Driver test suite as an addition to our testing coverage for DPDK at the UNH lab.

I have some questions about how to set the test suite arguments.

I have been able to configure the Test Engine to connect to the hosts in the testbed. The RCF, Configurator, and Tester all begin to run, however the prelude of the test suite fails to run.
The documentation mentions that there are several test parameters for the test suite, like for the IUT test link MAC, etc. These seem like they would need to be set somewhere to run many of the tests.

I see in the Test Engine documentation, there are instructions on how to create new parameters for test suites in the Tester configuration, but there is nothing in the user guide or in the Tester guide for how to set the arguments for the parameters when running the test suite that I can find. I'm not sure if I need to write my own Tester config, or if I should be setting these in some other way.

How should these values be set?

I'm also not sure what environment variables/arguments are strictly necessary or which are optional.

Regards,
Adam
